Have shorted circuit on fuse 15. This is one that has antenna, dome lights, and courtesy lights. Thought problem was with alarm system. Unplugged module with no change. Only clues to this mystery is the seatbelt warning light flashes continually when power is on. Have found light flashing with power off and doors closed. The switch for the map light/courtesy light doesn't work correctly. In one position the light comes on. Another it is off. in still another the passenger side light comes on. Have also unplugged antenna motor thinking there maybe a short there. No change. Have manual on CD. There is a anti thief module in the circuit that that appears to effect the circuit. Have no idea where it is located or how to test. Any suggestions?
